The San software holds the main data for most of BA's business applications, and the new monitoring software will tell IT staff how well it is performing, or if it is not functioning properly.
The company also installed software enabling it to make better use of storage space by searching and highlighting where there is space left to use.
David Smith, infrastructure software manager at BA, explained that the San has some resistance, so a single failure would not cause an outage of the entire system.
He said, "It would take multiple failures, but if we did not spot things quickly enough, some business functions like parts of BA.com or the finance system would not work at all.
"This software allows us to see if there is a problem and fix it before it causes us problems."
He said the measure could save them money, but said, "We have not put a figure on it as it is more of a cost avoidance."
The company is putting more services onto the San software as the website develops and the business grows. The new system allows BA to see where there is remaining space before having to buy more disks, giving it better management capability of the space it has and avoiding wastage. Smith said, "This tool will help us find that space very quickly and use it more appropriately".
New capacity licence software means the company only has to purchase extra licences as their storage requirements grow, instead of each time they buy a new server.
The software, provided by CA, includes CA Storage Resource Manager, CA San Manager, BrightStor San Designer and XOsoft WanSyncHA.
The software will be rolled out by the end of the year.
